Structural composition
The composition of the duckbill valve mainly consists of elastic
neoprene and man-made fibers, which are specially processed.
This structure makes the duckbill valve close under its own elastic
action when there is no internal pressure; As the internal pressure
gradually increases, the outlet gradually increases, thus keeping
the liquid discharged at high flow rates.
This design allows the duckbill valve to be widely used in a
variety of piping systems, as it effectively prevents the back flow
of liquids while keeping the fluid flowing smoothly.
